FIELD: metallurgy.
SUBSTANCE: invention relates to the method of obtaining of an electrolyser cathode pack for aluminium production. The method includes preparation of initial materials containing coke and powder of solid material such as, for example TiB2, and also, if necessary, carboniferous material, mixing of initial materials, formation of the cathode pack, carbonisation, graphitisation and cooling, note that graphitisation is performed at temperatures from 2300 up to 3000°C, in particular from 2400 to 2900°, and the second layer made with the thickness amounting from 10 up to 50%, in particular from 15 up to 45% of the total thickness of the cathode pack.
EFFECT: high wear resistance with reference to aluminium and cryolith, and decrease in energy consumption are provided.
